Previous Comments: ------------------------------------------------------------------------ [2001-12-12 13:01:17] gerald@ethereal.com As described in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=57421 recent versions (after ~August 2001) of the ucd-snmp packages redefine sprint_objid and sprint_value at the API and ABI level. PHP's SNMP module calls both of these functions. After building PHP 4.1.0 with SNMP support on a stock Red Hat 7.2 system, the following script dumps core: <? $sd = snmpwalk("<device address>", "public", ".iso"); echo $sd; ?> This affects all systems running Red Hat Linux 6.2 through 7.1 with updated ucd-snmp packages applied, along with stock 7.2 systems. Someone on the ethereal-dev mailing list reported that SuSE is affected as well. SNMP support must be compiled into PHP for it to be affected, of course.
